Lift Station No.3 Modifications Project No. 07-03:
Approve Natural Gas Generator Quote.
REQUEST (Simple Majority Vote Required)
Staff requests the City Council approve a quote for the generator to Quality Control
& Integration, Inc. in the amount of $39,005.63.
BACKGROUND
On August 27,2007, Council awarded the construction contract to Parrott
Contracting, Inc. for the Lift Station No.3 Modifications Project. Included in the
construction contract is the installation of the generator supplied by the City.
Lift Station No.3 is located on the north side of Trunk Highway7justwest of
Church Road. The station is currently being rebuilt and is the Il1aincollection point
for wastewater in the western portion of the city. Four smaller lift stations flow into
Lift Station No.3.
A standby generator is needed at Lift Station No.3. Thereasonf()Fthisneeclisthat
the power supply regularly is interrupted. During a power interrupti()ll,theutility
department needs to tend to this lift station first. . With the amount off1ow/etityrill~
this station and the distance from the public works facility, anypowerinterrugtiprLat
this station causes and immediate emergency. During peak traffictimes,the~e\V'er
could back up because of the extra time it takes to reach this sta.tion.Apptherre<i1>()J1
to have a standby generator at this location is because during citywide power
failures, the utility department can barely keep up with the mobilegelleratoFoftl1e
other 30 lift stations plus the wells. Having a standby generatoratthislocati()llwill
help prevent sewer backups during power interruptions.
The generator staff proposes to purchase for Lift Station No. 3is a natural gas unit.
This site is a good location for using natural gas versus diesel because Minnegasco
has a trunk gas line in'the Highway 7 right-of-way next to the lift station..Staff
anticipates future maintenance of the generator will be less then a diesel unit because
of diesel fuel related maintenance requirements. An environmental reason for going
with the natural gas is the proximity to the wetland. Using natural gas at this site
eliminates the chance of a diesel spill into the wetland.
The City of Chanhassen . A growing community with clean lakes, quality schools,a charming downtown, thriving businesses, winding trails, and beautifui parks. A great place to live, work, and play.

This lift station picks up 4 other smaller lift stations before discharging into the Metropolitan Council line. It is critical this lift station be in
operation even if power is interupted. A standby generator is recommended for this lift station for reliability. The City has other standby
generators. The City has 30 lift stations and it is difficult to operate all the lift stations with the City's few portable generators.
